The Introduction Of Digital Portable Hardness Tester
Apr 04, 2018


Digital Portable Hardness Tester Characteristics

Wide measuring range. Based on the principle of Leeb hardness testing

theory. It can measure the Leeb hardness of all metallic materials.

Large screen, showing all functions and parameters.

Test at any angle, even upside down.

With background light

Direct display of hardness scales HRB, HRC, HV, HB, HS, HL

Seven impact devices are available for special application. Automatically

identify the type of impact devices.

 Large capacity memory could store 500 groups (Relative to average times 32

~1 ) information including single measured value, mean value, testing date,

impact direction, impact times, material and hardness scale etc.

Upper and lower limit can be preset. It will alarm auto

value exceeding the limit.

 Battery information indicates the rest capacity of the battery.

Software calibration function.

Software to connect with PC via USB port.

Compact metal case, suitable for use under poor working co

Continuous working period of no less than 50 hours with two alkaline

batteries(AA size); Auto power off to save energy.
